Hi!
I was wondering if there was a way to return a substring (with offset &
count) on a field in a GET request? The problem I am hitting is, I have the
ID of the document, but I only want to retrieve N number of bytes from M
offset.

Thanks Simon. I'll then try and see if I can do it on the client side.

Hi, I have some quite large documents (about 30k) and I want to get only an _excerpt
of each document_, for example, 250 characters. It really does not matter
if they are the first 250 characters or a chunk in the middle. I would
prefer not doing it a client side to avoid these large documents moving in
the network. This thread looks very related.
Is there any progress on this (use a GET request) from March?
Can this be done with a preparedSearch or any other mechanism?
Looks something quite trivial to not have an easy response.
Thanks

Highlighting can return an excerpt from the beginning of the document if it
doesn't find a match in the document. You can't do that with an HTTP GET.
You still have to POST the search with the right highlihting configuration.

Hi Nikolas, yes, thanks, this is exactly my use case, i.e. when
highlighting does not match any term.
There seems to be something about this from 4 months ago:
[https://github.com/elasticsearch/elasticsearch/pull/3613](https://github.com/elasticsearch/elasticsearch/pull/3613) It looks that
config param was called no\_matches.
Any idea how to configure this with the Java API?

This seems a very recent addition[https://github.com/elasticsearch/elasticsearch/commit/14a709f563a264c4371392e31c7bee9d26758056](https://github.com/elasticsearch/elasticsearch/commit/14a709f563a264c4371392e31c7bee9d26758056) to
ES and the config param finally called no\_match\_size. It looks like that
the way to define this is in a Highlighter Field as follows:
HighlightBuilder.Field field = new HighlightBuilder.Field("text")
.fragmentSize(21)
.numOfFragments(1)
.highlighterType("plain")
._noMatchSize(20);_
and, in the SearchRequestBuilder assign this field as follows:
...
.addHighlightedField(_field_)
...
Unfortunately my ES 0\_90\_5, HighlightBuilder still does not contain this
method noMatchSize
[https://github.com/elasticsearch/elasticsearch/blob/14a709f563a264c4371392e31c7bee9d26758056/src/main/java/org/elasticsearch/search/highlight/HighlightBuilder.java#L455](https://github.com/elasticsearch/elasticsearch/blob/14a709f563a264c4371392e31c7bee9d26758056/src/main/java/org/elasticsearch/search/highlight/HighlightBuilder.java#L455)so
it looks that I have to upgrade my ES to latest release.
To be confirmed....
Regards.

Tested with 1.0.0.beta1 but does not seem to be working.
For the query below, the highlights are returned successfully when the
record matches _key_. However, despite \*setHighlighterNoMatchSize(250) \*has
been set, unmatching records does not return 250 characters from the start
of the record as expected.
return getClient().prepareSearch()
.setQuery(QueryBuilders
.boolQuery()
.should(QueryBuilders.matchQuery("column", _key_))
)
.setFilter(FilterBuilders.idsFilter("vertex").ids(array))
.addHighlightedField("column", 250, 1)
- .setHighlighterNoMatchSize(250)\*
.execute()
.actionGet();
Any idea?
Thanks

Tested in 0.90.9 (December 23, 2013) as seems newer than 1.0.0.beta1 (November
6, 2013) and same issue: no highlighting results when key does not match,
despite _setHighlighterNoMatchSize(250) has been set._

Can you please elaborate a bit? Will this be available in future releases?
